Abstract:We present an improved calculation of B → light pseudoscalar formfactors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading order twist-4 corrections. The total theoretical uncertainty of our results at zero momentum transfer is 10 to 13% and can be improved, at least in part, by reducing the uncertainty of hadronic input parameters, in particular those describing the twist-2 distribution amplitudes of the π, K and η. We present our results in a way which details the dependence of the formfactors on these parameters and facilitates the incorporation of future updates of their values from e.g. lattice calculations.

We present a systematic study of twist three light-cone distribution amplitudes of vector mesons in QCD, which is based on conformal expansion and takes into account meson and quark mass corrections. A complete set of distribution amplitudes is constructed for ρ, ω, K * and φ mesons, which satisfies all (exact) equations of motion and constraints from conformal expansion. Nonperturbative input parameters are calculated from QCD sum rules, including an update of SU(3) breaking corrections in the leading twist distributions.

Following Ohrndorf [18], we define a set of eigenstates |j, m with conformal spin j and the "third projection" of the spin m = j, j + 1, j + 2, . . ., such that J 3 |j, m = m|j, m , J 2 |j, m = j(j − 1)|j, m , J − |j, m = −(j − m)|j, m − 1 , J + |j, m = (j + m)|j, m + 1 .

The rare decay B → K * (→ Kπ)µ + µ − is regarded as one of the crucial channels for B physics as the polarization of the K * allows a precise angular reconstruction resulting in many observables that offer new important tests of the Standard Model and its extensions. These angular observables can be expressed in terms of CP-conserving and CP-violating quantities which we study in terms of the full form factors calculated from QCD sum rules on the light-cone, including QCD factorization corrections. We investigate all observables in the context of the Standard Model and various New Physics models, in particular the Littlest Higgs model with T-parity and various MSSM scenarios, identifying those observables with small to moderate dependence on hadronic quantities and large impact of New Physics. One important result of our studies is that new CP-violating phases will produce clean signals in CP-violating asymmetries. We also identify a number of correlations between various observables which will allow a clear distinction between different New Physics scenarios. * wolfgang.altmannshofer@ph.tum.de † Patricia.Ball@durham.ac.uk

Using improved theoretical calculations of the decay form factors in the light cone QCD sum rule approach, we investigate the decay rates, dilepton invariant mass spectra and the forward-backward ͑FB͒ asymmetry in the decays In particular, the presently allowed large-tan ␤ solutions in SUGRA models, as well as more general flavorviolating SUSY models, yield FB asymmetries which are characteristically different from the corresponding ones in the SM.
